CamelBak
Blowfish

Details

CamelBak's Blowfish goes from small to big in a snap, so you'll always have the right sized pack. The large main compartment expands for extra carrying capacity—if you want a more streamlined bag, just zip it up! Plus, its 70-ounce Antidote reservoir is easy to fill, while a ventilated back panel keeps you feeling fresh. And, the waist and sternum straps offer excellent support and stability for all-day comfort.
